Volcano in the eastern Pacific
Since 1977, many hydrothermal vents are found in the coastal region of volcanoes in the eastern Pacific. The waters around these vents, which can reach temperatures of around 380 degrees Celsius, inhabited by a unique ecosystem. Depth research shows that bacteria are able to live from the oxidation of hydrogen sulfide is the basis of the food chain in the region. Hydrogen sulfide (a gas that emit an odor similar to rotten eggs) are needed as a food ingredient by these bacteria, many gas contained in magma, coupled with a slight (15%) resulting from the reaction of sulfur (SO4) contained in seawater. Thus, the energy that supports life in the deep sea is not energy-Photosynthesis sunlight but the energy of a chemical reaction-chemosynthesis
